| Accoustic Modifier |
 |
The horn effect was first applied to earmolds in the late 1950's with the development of products similar to today's Accoustic Modifier or high frequency short canal / wide bore earmolds. This mold can be easily altered by the dispenser, allowing variable control over the high frequency response in any given fitting. For best results it is suggested that a S.A.V. or P.P.V. venting system be used with this style. |

| Belled Canal or Horn Bore |
|
The most basic of horn effects are the laboratory belled bore canal and the simple horn bore. These are options in any earmold style and are especially important with wide band receiver aids to preserve the high frequency signal. Can come in 3mm and 4mm opening. |
